oven temp adjustment for pyrex

A sudden change in temperature is what breaks glass, not the temperature per se. Failure to preheat the oven is the most common cause. Remember back in Chem Lab heating Pyrex flasks with a Bunsen burner?

I've recently had a couple of pyrex explode in the oven. I think it shouldn't be more than 375 degrees - I recall mine exploding around 400.

I drop the oven temp 25F when I use glass containers.

Ah, I guess I misremembered. Thanks!

No oven temp adjustment needed as far as I know. Just avoid adding really cold (like right out of the freezer)into a hot oven. Here's the pyrex guidelines for use,http://www.pyrexware.com/index.asp?pageId=32
